Hi pafurijaz, I thought it should only be necessary to use your system's package manager to install Wine. Once Wine is installed you should then be able to run the MoI Windows version .exe installer directly.

Then whether it's going to work well or not depends on the quality of your video driver.

Are there some distros where it is difficult to install Wine?

This script looks like it installs some things which shouldn't be needed for running MoI like winetricks, mono, and gecko. Just a plain regular Wine install should be all that you need.
